Determination of ziram in vegetable samples by square wave voltammetry

The electrochemical behaviour and electrode reaction mechanism of ziram (zinc-dimethyl dithiocarbamate) on a hanging mercury drop electrode were investigated in Britton-Robinson (B-R) buffer by using cyclic and square wave voltammetry (SWV). Based on these studies a voltammetric method for determination of ziram was-developed and applied to determine the ziram in synthetic and spiked vegetable samples, satisfactory results were obtained in both cases.
